A transmitting wideband DBF algorithm based on time-domain filter

Abstract

A novel transmitting wide DBF algorithm based on time-domain filter is presented in this paper. The mature FIR filter was used to form transmitting wideband digital beam in time domain. The signal with continuous phase cannot be transmitted by frequency-domain algorithm. The right beam direction in non-reference frequency point couldn't get by adaptive filter algorithm. Many flaws in traditional method can be overcome by the method in this article. Finally, the practicability and validity of the proposed algorithm were proved by computer simulation.
